The figure above shows an irregular hexagon with the equation (the shape includes both orange and yellow points, I made the borders yellow so that it is easier to see the lines that form the sides): $$(-4 \leq x \leq 3) \cap (1 \leq y \leq 2) \cap (-1 \leq z \leq 4)$$ Regular Hexagons The equation of a regular hexagon with centre c can be written in a very simple form: $$|\bv v \bv c| \leq r$$ In the hex world, all points within a distance r of some point form a regular hexagon
Think of short-acting substances like light switches, meaning theres an immediate on/off action that stops the moment the drug is cleared
